ID: 20924 Comment by: 2072 at 2072productions dot com Reported By: a_villacis at palosanto dot com Status: Bogus Bug Type: Scripting Engine problem Operating System: Linux 2.4.7-10 PHP Version: 4.3.0RC2 New Comment:
Well this is maybe not a bug but it is a real problem when you use the pcntl extension to handle signals where you have to put a declare(ticks=1); for the whole script... I think something has to be done with pcntl signal handling to fix that because it's really annoying. Previous Comments: ------------------------------------------------------------------------ [2002-12-24 11:57:06] [EMAIL PROTECTED] Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is actually not a bug. Because the declare() stuff works as some kind of conditional compile the functions will not be defined during parsing/compile, but only when the code is executed for the first time. Of course when the postdefined_in(); is reached the code below has not been executed before and thus you can an undefined function error. The same would happen if you'd put it in an if like this: <?php if (TRUE) { function blah1() { } blah1(); blah2(); function blah2() { } } ?> ------------------------------------------------------------------------ [2002-12-24 11:44:23] a_villacis at palosanto dot com Same problem with 4.3.0RC4. ------------------------------------------------------------------------ [2002-12-12 11:46:22] a_villacis at palosanto dot com I just upgraded to version 4.3.0RC3 with the same configure command, but the script gives the same message as in the original posting. This behavior is rather annoying, but a workaround is to declare the troublesome procedure *outside* the scope of the 'declare(ticks=1) {}' block. However, this does not seem to help if the new syntax 'declare(ticks=1);' is used to cover the entire script under the declare() scope.
